Setting security permissions for apps

BlackBerry 10 OS includes application permissions that are designed to let you
control the information and features that an application can access on your BlackBerry device. For example, you can control whether an app can access your
email, contacts, pictures or the location of your device. Keep in mind that some
applications require specific permissions to work. You can also help safeguard your
device by downloading apps only from trusted sources, such as the BlackBerry World storefront.

When you open an app for the first time, your device might display a list
of the files and features that the app wants to access. If something doesn't seem right
to you, you can reject the app's request to access an item. For example, you might
download a game that requests access to your messages, which might make sense if the
game includes a feature to share your game score. However, if you aren't comfortable
with the game having the ability to compose and view your email messages, you can turn
off access to messages or delete the app. You can view or change permissions for most
apps in your device settings.

For some apps, when you install the app, you are prompted to accept or
decline all of the requested permissions. If you decline, the prompt will appear again
the first time you open the app. You can't change the application permissions later
unless you delete and reinstall the app.
